Abstract
A welding machine for automatically welding abutting workpiece portions in which the workpiece portions are aligned by a gauge and after being clamped in such a position, the gauge is automatically removed and the clamped ends are moved into abutting relationship to each other to be welded together. After the weld is completed the gauge is moved automatically to engage and eject the welded part and at the same time position the gauge and place the machine in condition to receive the next part to be welded.
Claims14
In a machine for welding adjoining workpiece portions together comprising;
- a gauge means movable between first and second positions, clamp means for each of said workpiece portions disposed at opposite sides of said gauge means and being operable to grip said portions and hold said portions in engagement with said gauge means when the latter is in said first position, means to move said clamp means toward each other when said gauge means is in its said second position to move said workpiece portions into abutting relationship to each other, a welding head movably supported for movement in close proximity to the abutting workpiece portions, means to move said welding head for welding said workpiece portions to each other to form a finished workpice, said clamp means being releasable from said workpiece portions and movable away from each other in response to movement of said welding head to a position completing the weld, said gauge means being movable to its first position and between said clamp means upon movement of said clamp means away from each other to engage said workpiece and eject it from said machine, said clamp means each comprising a support member and a clamp element movable relative to said support member, said clamp element and support member at one side of said gauge means being movable to grip one workpiece portion and being movable therewith as a unit relative to the other of said clamp elements, support members and workpiece portions upon movement of said gauge bar to said second position, said support member and clamp element at one side of said gauge means gripping one portion of said workpiece with a given force and the other of said clamp elements and support members gripping the other portion of said workpiece with a lesser force to permit sliding movement of said other portion in said clamp means when said portions are brought into abutting engagement with each other upon movement of said clamp means toward each other.
A machine for welding adjoining workpiece portions together comprising, gauge means movable between a first and second position, a pair of clamp means to clamp each of said workpiece portions disposed at opposite sides of said gauge means and being operable to grip opposite surfaces of said portions and hold said portions in engagement with said gauge means and in alignment in the same plane when the gauge means is in said first position, said gauge means having a predetermined width, means to move said clamp means towards each other when said gauge means is in said second position to move said workpiece portions towards, each other, said clamp means being movable a distance greater than the thickness of said gauge means to bring said workpiece portions into tight abutting relationship with each other and wherein one workpiece portion slips relative to its associated clamp means upon relative movement of said clamp means towards each other, a welding head supported for movement in close proximity to the abutting workpiece portions, and means to move said welding head for welding said workpiece portions to each other to form a finished workpiece.
